Summary: In the paper the findings of leptospira antibodies in swine
of four biocenoses and in cattle of two biocenoses are presented as well as
in small terrential mammals from their environment.Antibodies were faund in
3318 swinw out of 12566 examined and in 174 cattle out of 1010 examined.Out
of 536 small mammals examined the antibodies werw found in 106 and 47 were
established as carriers.In 436 cattle of I biocenosis antibodies for
sv.gripp.were found in 56 and in 3 small terrential mammals out of 151
examined.Out of 574 cattle of biocenosis II antibodies for
sv.icterohaemorr. were found in 4,pom.in 56,gripp.in 45 and sej.and sax.in
2 of them.In 3O small terrential mammals antibodies for sv.pom.were found
in one of them and sej.in 2.In 3685 swinw in biocenosis I antibodies for
sv.icterohaemorr.were found in 695,pom.in6,aust.in 619,tarass.in 26 and
ball.and can.in one of them.In 151 small terrential mammmals serovar for
icterohaemorr.was found in 72 of them,ball.in4,sej.in 6,sax.in 5 and
aust.and pom.in 1 respectively.in 1671 swine of biocenosis II antibodies
for sv.icterohaemorr.were found in 39 of them and tarass.in 5.In 100 small
terrential mammals examined antibodies forsv.icterohaemorr.were found
in7,aust.and pom.in 5 respectively,hardjo in 4,can.,ball.,gripp.,sej.and
sax.in 3 and tarass.in 2 of them.In 4889 swine of biocenosis III antibodies
for sv.icterohaemorr.were found in 451,pom.in311,aust.in 712, tarass.in
832,ball.in 3 sej. and bat.in 2 and gripp.and sax.in 1 of them.In 113 small
terrential mammals antibodies for sv.pom.were found in 12 of them,for
sax.in 4,bat.and sej.in 2 respectiveli,and icterohaemorr.in1.In 2323 swine
of biocenosis IV antibodies for sv.icterohaemorr.were found in 119 of
them,pom.in 64,aust.in 184 and tarass.in 22 of them.In 47 small terrential
mammals antibodies for sv.pom.were found in 3 bat.in two of them. Comparing
the anibody findings for serovar in cattle and small terrential mammals it
iis evident that antibodies for sv.hardjo and icterohaemorr.were not found
in small terrential mammals. Antibodies for sv.can.were found in swine but
not in small terrential mammals where antibodies for sv.hardjo were
found,which however were not found in swine ,and also the same
sv.leptospirosis were not present in all biocenosis.The findings of same
antibodies for sv.leptospires in cattle,swine and small terrential mammals
indicate that the infection was transferred from one species to
another,which was supported by the findings of carriers in small terrential
mammals.

Research goals: In endeavoring to eradicate contagious diseases in
domestic animals or at least minimize their outbreaks,it can happen that
the results wished cannot be always achieved.In some cases the cause lies
in the connection between game,the carrier of the contagious disease,and
domestic animals.That means that the infection in wild animals in one
biocenosis could effect the incidence and spreading of infective disease in
domestic animals. Hence,the chain of transferring the carrier of the
disease is maintained muttualy by domestic and wild animals.One of such
diseases is also leptospirosis.Although it is well known that domestic and
wild animals are the carriers of leptospirosis, it is not known to which
extent in particular biocenoses wild animals influence the incidence and
spreading of leptospirosis in domestic animals and whether the same
sv.leptospires occur by them.In our country leptospirosis is spread in
breedings of domestic animals.The percentage of infected animals even
exceeds 30%.The varieties of sv.leptospires incidence in particular
breedings make the control even more difficult.It can happen that in
breedings infected with one serovar another infection occurs and an
explanation can hardly be found.For that reason despite the precautions
taken for preventing the incidence and spreading of the infection in
breedings the infection cannot be eradicated. Our aim is to continuously
monitore the presence of antibodies for leptospires in cattle and swine
breeding.After that,to establish the presence of antibodies of leptospires
in small terrential mammals living in the area where domestic animal are
kept,and to isolate leptospires from their organs.By continuous monitoring
one biocenosis we could get a picture on the frequency of leptospirosis in
them and their identity or dissimilarity in particular species.By this
investigation a cognition could be reached on which furter strategy for
protection of domestic animals from leptospirosis could be based. Other information about the project.
